Abstract (en)
[origin: EP2228189A1] The method involves introducing a core pipe into a cavity of a mold. One of the ends (3,4) of the two non-lost core units (17,18) is arranged respectively against the connection openings in a sealing manner. A non-lost core unit (19) is arranged with one end against a docking opening in a sealing manner. The plastics material is introduced into the mold cavity to encapsulate the core pipe. The core units (17,18) and the non-lost core unit (19) are withdrawn from a hollow body (1) that is created once the plastics material is cured.
